To aZZ 'who/m, t may concern.'

Be it known that I, ROBERT SMITH AtLqoefAn, citizen of the'United lStates of Amerlca, residing at Louisville in the county of Jefferson and State of lKentucky, haveinvented .certain new and useful limprovements 1n Cast-Metal Ends for Conveyer Rollers, of

which the following is a specification.

'lhisv invention relates to rollers for conveyers, but more particularly to a novelend object tov provide a metal end cast in the I roller itself and around asteel bearing-bushin e 'he invention consists of the novel construction of theend of the roller, and .in theA method of centering. the steel bushing, and

of casting the metal end. within the Y,roller and around .the centered bushlng.

struction which provides for locking the cast end within the tubular roller to prevent looseness of 4the end and rattling of the -trating it in same; all of which, will be first fully described and afterwards specifically pointed out in the appended claims. y

Referring to the accompanying drawlng: Fig. 1 is a vertical sectional view through the end-portion of a conveyer roller, illusposition to receive an end cast therein, and

F ig. 2- is a vertical longitudinal view through the completed roller.

Like numerals of reference indicate the same partsl throughout the two figures, in which:

1 indicates a hollow metal conveyer roller, 2 the metal ends,l 3 the shaft, 4a the roller bearings and cages.

. The roller 1 is provided. near its ends with a plurality of inwardly bent tongues 6, preferably struck in from the wallof the roller itself, so as to provide av plurality of persectional roller, although other suitable interlocking .means may be provided. The cast metal ends 2 are formed with integral lugs 7 lying within said perforations 6; each end being centrally provided with a steel bushing 8 to receive a roller bearing and cage 4. The steel bushing 8'commun1cates with a smaller .opening or bore '9 through -which the shaft 3 extends; an annular shoulder 10 being formed at the bottom of the steel'bushing The invention further consists of the con- Specification of Letters Patent. Patented May 30g, 1922i.

vfor ther-etention of the roller bearing and size to snugly receive the end. portion of the roller 1, and its perforation's 6'; a gate 17 'being provided 1n saidblock 15 so as to communicatewith one fof theperforations 6 in the" manner as shown in Fig. 41. A metallic. core 18 having a steel bushing 8 thereon is centered within the endof thev roller, for instance as shown in Fig. 1; said core being of a predetermined. diameter and having a shoulder 19 and a smaller tapered por-l tion'20 as shown'-The end portion of the roller 1 being positioned as. illustrated in Fig. l, molten metal is poured into the gate 17 and flows through the coincident perforation 6 in the roller 1 in to the end portion of the roller, around the steel bushing 8' centered on the core 18 and into the perforations 6 the metal rising in the end portion of the roller up to the top surface of the block15,4 as 'indicated inFig. 1. The in- .wardly bent tongues 6, thus liel within Ithe molten metal, and upon the cooling and contraction of the metal-,end 2, the same con- 'tracts against the outer surfaces of the `tongues 6, as will be 'apparent from the drawing and thus creates a rigid interlocking lof the end 2 with the roller 1, preventing any loosening and'rattling, so that the end 2 becomes practically an integral part ofthe roller.

The end 2 being thus cast into the end portion ofthe lroller 1, the roller 1 is then removed from the block 15, and that portion of the cast metal which was within thel gate 17, is knocked off. rThe end 2 thus ,formed with the steel bushing centered therein, is ready to receive the roller bearing 4. l

This method provides a most eective end for the roller, and incorporates a factor of strength far in excess of all requirements,

while its application to the roller by the method disclosed anchors the end in the roller and contracts the metal thereof around 'the bushing 8 as tov preclude any. possibility of casual. displacement'of the bushing.

Having thus. described the invention, what -openings in the roller, and a central metal bushing' in each cast metal end for the reception of a bearing.

2. A conveyer roller including` a tubular body provided near each end thereof with an opening transversely through the Wall of the roller, a cast metal end in each end portion of the roller, leach cast metal end including a lug entering the said opening in the roller and including a metal bushing within each cast metal end for the reception of a bearing.` 3. A conveyer roller including a tubular body provided near each end thereof with a depression in the wall surface of the roller, a cast metal end in each end portion of the roller, each cast metal end including means cooperating with the depression in the roller wall to lock the cast metal endvwithin the roller, each vcastnietal end including a central metal bushing within the same for the reception of a bearing, the cast metal end being contracted around the said bushing to retain the bushing against displacement.

4. A conveyer roller including a tubular body, a central metal bushing for the reception of a bearing, and a'cast metal end between the tubular body. and the central bushing, said' cast metal end being contracted around the said bushing to retain the same against displacement.

5. A conveyer roller including a tubular body provided near each end thereof with a plurality of openings transversely through the Wall of the roller, a cast metal end in.

each end portion of the roller, each cast metal end including lugs entering the said openings in the roller, and includinoF a central chamber for the reception of 'a bearing.

6. A conveyer roller including a tubular body provided near each end thereof with an opening transversely though the Wall of the roller, a cast metal end in each end portion of the roller, each cast metal end including a lug enterin the said opening in the roller and also inclqudingr a central chamber for the reception of a bearing.

7. A conveyer roller including a tubular body provided near each end thereofwith a.

depression in the wall of the roller, a metal end cast in each end portion of the roller, each cast metal end including means cooperating with the depression in. the roller Wall to lock the cast metal end`.within the roller, each cast metal end 'includinga central chamber for the reception of a bearing. 8. conveyer roller including a tubular body provided near each end thereof with an inwardly extending tongue, a metal end cast in each end portion of the roller and in interlocking engagement with said inwardly extending tongue,A each cast metal end including a central chamber for the reception of a bearing.

9. A conveyer roller including a tubular body provided near each end thereof with an inwardly extending member, a metal end cast in each end portion of the roller and surrounding said inwardly extending member to form an interlockingv engagement therewith, each cast metal end includino means to receive a bearing.
